Parker’s A-LOK® reducing couplings with dual clamping rings are designed to provide reliable, leak-free connections in instrumentation, process and control engineering, and analytical applications where a pipe coupling with two clamping rings is required. The couplings are manufactured to high-quality standards and are available in a wide range of sizes, corrosion-resistant materials, and configurations.
Parker A-LOK® reducing couplings are manufactured as standard in heat-code-traceable 316 stainless steel. Other available materials include 6Mo, Alloy 825, Alloy 625, and Alloy C-276.
The fittings are available for inch-sized tubes with outer diameters ranging from 1/8″ to 1″, as well as for metric tubes with outer diameters ranging from 3 mm to 25 mm.
